The Rio Verde area is beautiful, you are first hiking up and then descending the river itself. The organizers made sure everyone could descend to his/her ability. Safety was addressed thoroughly. There was room to do some higher jumps.
Just the right level of scary, rewarding, and fun. Raul was a great guide that even provided enough reassurance for my wife to jump off a cliff into a rock pool.
Rio verde is a wonderful area; the hike up is already a pleasure, the canyoning down is spectacular; beautiful sights, cool jumps, rapids and slide throughs.
